50DTV / 75CATV are officially on the commercial at every country in world from 2007.Temwell is famous VHF．UHF Band Pass Filter maker.
Because the marketing's requirement.We provide the 50 Ω / 75Ω BW which 30MHz / 40MHz / 60MHz / >100MHz of each Frequency 100~860MHz series on sale for your choice to use.
As you know each country permits DTV Channel is different.Therefore：
BW > 30 MHz is protected any of 4 Channel from 100~900 MHz.
BW >40MHz is protected anoy of 5 Channel from 300~1000 MHz.
BW >60 MHz is protected any of 8 Channel from 300~1000 MHz.
Bw >100 MHz is protected any of 13 Channel from 300~1000 MHz.
(1) -1dB BW: 30MHz-40MHz (75Ω) Series : 100~400MHz
